Mechanical/ Electrical Engineer

Avant Robotics USA
Boston, MA Full Time
POSTED ON 4/23/2026
AVAILABLE BEFORE 5/22/2026

What you'll be doing

  • Build, iterate, and debug mechanical and electromechanical subassemblies for humanoid robot prototypes — joints, transmissions, end-effectors, sensor mounts, cable routing, and structural components.
  • Fabricate parts in-house using the full shop: CNC milling, lathe work, waterjet cutting, 3D printing, laser cutting, drilling, tapping, and general machining.
  • Own your CAD-to-part loop — design a component in SolidWorks or Fusion 360, translate it to CAM, machine it, verify tolerances, and assemble it onto the robot.
  • Work closely with our mechanical design lead and robotics software team to support rapid prototyping cycles. You'll often be the person who makes "we need this bracket by tomorrow" actually happen.
  • Maintain and upgrade shop equipment; help set up and organize our in-house fabrication space as the team grows.
  • Assist with basic electrical work: wiring harnesses, connector crimping, PCB assembly / rework, sensor integration.
  • Participate in robot bring-up, integration, and hardware troubleshooting alongside senior engineers.

What we need to see

  • Bachelor's or Master's degree in Mechanical Engineering, Electrical Engineering, Mechatronics, or a closely related field.
  • Demonstrated hands-on shop experience — CNC milling, manual machining, waterjet, 3D printing. We need to see evidence of parts you've actually made, not just designed.
  • Solid CAD fluency in SolidWorks or Fusion 360, including parametric modeling, assemblies, and technical drawings.
  • Working knowledge of CAM software (Fusion 360 CAM, HSMWorks, or similar) — able to program toolpaths and run parts on a CNC mill without supervision.
  • Comfortable reading electrical schematics, using a multimeter and oscilloscope, and doing basic soldering / crimping / wire routing.
  • A "builder" mindset — you'd rather make a part in the shop than order it and wait a week.
  • Clear communicator who can work alongside robotics software engineers and explain trade-offs between design, manufacturing, and cost.

Ways to stand out

  • Experience in a university robotics lab, FSAE / Formula Student team, robotics competition (FIRST, BattleBots, FRC), or maker space — where you've built real robots, not just simulated ones.
  • Experience prototyping or building humanoid robots, legged robots, robot manipulators, or dexterous hands.
  • Familiarity with actuators (BLDC motors, harmonic drives, cycloidal reducers, tendon-driven systems) and transmission design.
  • PCB design experience (Altium, KiCad, or Eagle).
  • Exposure to embedded systems — STM32, Arduino, Raspberry Pi, Jetson — enough to bring up a custom board or read sensor data.
  • Comfortable in a fast-moving, early-stage environment where scope shifts week to week.
